Process Water Deoiling

KPE provides engineered solutions -either skid mounted or site executed- for water deoiling systems in all applications of water treatment
either produced water, condensate water, and raw water oil removal.

A wastewater stream may contain oil in three major forms: Free, Emulsified and Dissolved.
Free oil is so that the globules can rise as a result of buoyant forces and form an oil layer on top of water. 150 microns in size is
a defined benchmark for API Separator.
Smaller free oil and emulsified oil are in the form of much smaller oil droplets with diameter less than 20 microns, which form a
stable suspension in water as a result of predominance of inter-particle forces over buoyant forces, and no separate oil phase will form.
Emulsified oil may be removed by Coalescer Filter  or IGF Separator or by Chemical Injection, but not by gravity .
separation alone Dissolved oil is the petroleum fraction that forms a true molecular solution with water, and cannot be removed by gravity
separation; further wastewater treatment (for example, biological treatment) is necessary if removal of dissolved oil is required.
